A young man stands in his bedroom posing in front of a mirror. In his left hand he holds a machete, he takes a photo. Satisfied with his snap he lifts the weapon in both hands poised to strike, his face contorts into one of malignant rage, he takes another photo. Is this the latest ISIS recruit? A school shooter’s manifesto? A bad taste art project? No, this is 'POV ur a TERF in my mentions' the latest trend in trans activism.
